Anritsu, in collaboration with Tektronix, demonstrated a PCIe 6.0 base specification test system at last month’s PCI-SIG Developers Conference. The test setup teamed Anritsu’s MP1900A signal quality analyzer with a DPO70000SX real-time oscilloscope from Tektronix and silicon-proven Synopsys PCIe 6.0 IP.
PCIe 6.0 employs forward error correction (FEC) as a key technology to ensure the integrity of 32-Gbaud PAM4 (64 Gbps), low-SNR signals affected by transmission path loss. The demonstration highlighted an efficient test solution employing automatic base specification calibration and signal quality evaluation by the DPO70000SX scope, combined with the MP1900A’s error-correction analysis to measure FEC symbol errors in real time.
The MP1900A was used to generate a stressed compliant signal calibrated by the DPO70000SX scope based on the PCIe 6.0 base specification. The signal was then transmitted to the Synopsys PCIe 6.0 IP to measure bit errors using the DUT internal error counter. Additionally, bit errors were measured by the MP1900A PAM4 error detector in DUT loopback mode. With its forward error correction (FEC) function, the MP1900A analyzed and displayed FEC corrected/uncorrected errors and post FEC error rate, while the Tektronix real-time scope analyzed the signal waveforms from the DUT.
